brake lights

Hmmm, this doesn't really fit in any of the sub-forums, but here it is anyway. Having a problem with my Tundra's brake light. The tail light/brake light functions are shared by one bulb, turn signal is a different bulb altogether. When I turn on the headlights, the tail light comes on just fine. But when I step on the brakes, the light does not get brighter.

OK, sort of semi-related...now when I step on the brakes, my headlights dim a little for a second. Happens most when I step on the brake, a little less when I turn on the heater. Electrical short somewhere maybe? Any idea how to check where?
